Method of manufacturing a multielement acoustic probe using a polymer film metallise and ablate as ground plane

摘要

.The invention concerns a method for making an acoustic probe comprising single-unit piezoelectric transducers. The method comprising an original step, which consists in producing a ground plane consisting of a dielectric flexible film, covered with a conductive film. The dielectric flexible film is locally ablated to expose the conductive film. The thus ablated film serves as skin packaging and ground plane for the single-unit piezoelectric transducers. The invention is applicable to small-dimension endocardial echographic probes.
